B-20 MANUAL OPERATION
5)
Select the zero return mode (
) with the MODE
selection switch.
6)
Set the rapid traverse rate to be used for zero return
operation using the RAPID OVERRIDE switches.
For manual operation, the maximum allowable
override value is 50%. Therefore, if the
(100%) switch is pressed, the override value is
50%.
7)
Press and hold down the AXIS DIRECTION switch
(zero return direction) for the axis which is to be fed
to the zero point.
As the axis approaches the zero point, it
decelerates automatically and is positioned at the
zero point.
If an AXIS DIRECTION switch that moves the axis
in the opposite direction of the zero point is
pressed, the axis does not move.
The STATUS indicator
[X]
or
[Z]
is lit, or the status
indicator
[B-AXIS ZERO POINT]
(S type) on the option
panel is lit when the axis has been returned to the zero
point.
For the C-axis zero return operation, refer to
page B-85 (14-5). (MC type)
